| effect and mechanism | 1. Sodium hydroxymethyl sulfonate (PN) is a kind of high molecular polymer, which should be used with SP, M, N, P, AESS, GISS and so on. 2. It has a strong cathodic polarization, can significantly enhance the brightness of the low area, the use of PN found that the lack of brightness, can be appropriate to increase the amount of high level agent (polydisulfide). 3. PN is the most excellent high temperature carrier in acid copper brightener, which is suitable for complex workpiece electroplating. 4. In the range of 15 ℃ ~ 45 ℃ can be used, PN is not only suitable for acid copper, but also can be used for cyanide-free zinc plating brightener. 5. Complexing agents for heavy metals in nickel plating. 6. Sodium hydroxymethyl sulfonate can effectively complex copper, zinc, lead and other metal ions. Lead-Zinc Ore flotation lotion and color photo aids (anti-pollution and fading), Cotton printing industry. 7. No SO32-, with impurity removal, position, soft function. |
| Use | used in the production of pharmaceutical cancer enemy-M, sinovanamine and sodium isoniazid sulfonate. used as electroplating additive intermediate, used in the preparation of nickel plating brightener nickel plating brightener, can improve the brightness and leveling effect |
| production method | Add distilled water and formaldehyde solution to the reaction pot, cool to below 15 °c, add sodium bisulfite in batches with stirring, the reaction temperature was controlled at 60-65 ° C. For 20min, and the pH value was about 9 with sodium hydroxide solution. After completion of the reaction, hydrochloric acid was added to bring the pH to about 3. Activated carbon was added to decolorize and filter, the filtrate was cooled, ethanol was added to precipitate solid, placed, filtered the next day, washed with ethanol, and dried to obtain a finished product. |
